I can install FreeBSD if it's required.
Might be. I'm not really familliar with the Linux acpidump tool, but if it dumps all the tables in raw format, it might be useful. The mailing lists will strip attachments, so best if you put it on a webserver somewhere from where we can download it. Anyway, what we need to figure out is why mapping the RSDT table fails. If you happen to have some hacking skills you could try to figure out which "return NULL" in sys/dev/acpi.c:acpi_maptable() you're hitting on that laptop.
